t’s not actually going to be a standard, per se, because you can’t pass regulatory standards through reconciliation. Instead, it’s going to be a system of fines and payments that will incentivize utilities to increase their proportion of renewable energy to meet the targets. It’s called a clean electricity payment program (CEPP). A CEPP actually has some advantages over the traditional CES’s and renewable portfolio standard (RPSs) commonly seen in states. For one thing, it’s more progressive: the money to drive the transition comes from federal coffers (via taxes on corporations and the wealthy) rather than from electricity rates, which are regressive.
If you are paying for transition from taxation like this, because it's largely coming from richer members of society it's more progressive than tacking the charge onto every kilowatt used by consumers, which disproportionately affects lower income groups
